The Coast Guard’s director of prevention policy announced publication in the Federal Register of plans to cease broadcasting the North American Loran-C signal Feb. 8.
As a result of technological advancements and the emergence of the U.S. Global Positioning System, Loran-C is no longer required by the armed forces, the transportation sector or the nation’s security interests, and is used by only a small segment of the population, the Coast Guard said in a release. President Barack Obama’s fiscal year 2010 budget supported the termination of outdated systems and specifically cited the terrestrial-based North American Loran-C system as such an example. The president did not seek funding for the Loran-C system in fiscal year 2010. Termination was also supported through the enactment of the 2010 Homeland Security Appropriations Bill.
